To all fro/tom it may concern.'

Be it known that I, MnnToN H. GRnEsoN, a citizen of the United States, and a resident of Tampa, in the county of Hillsbor-y ough and State of Florida, have made Cer-` tain new and useful Improvements in Ball- Cocks, of which the following is a specification.

My present invention relates generally to ball cocks, the ordinary construction and uses of which are well known and is more particularly of the noiselesstype described and claimed in my Patent 1271459, granted July 2, 1918, and upon whichr the present application is an improvement.

The primary object `of my present im` provementsis the rearrangement and dis-4 position of the parts, with the purpose in view of having the valve to seat not only in the direction of flow of water, but also in a downward direction so that it is capable of closing by its own weight, and will remain closed and tightly held by the water pressure and its own weight as long as unaffected by the float controlled connections.

A further object in connection with the ball cock of the above description is the provision of float controlled connections, and a mounting therefor so arranged that the float with its stem and the valve shifting head may be removed for purposes of repair whenever it is desired to do'so, without affecting the valve in closed position. p With these objects among others, my invention in its most specific aspect resides in the features of construction, arrangement and operation to be now described with respect to the accompanying drawing forming a part of this specification, and wherein:

Figure 1 is a sectional view illustrating the practical application of my invention;

Fig. 2 is an enlarged vertical section through my improved ball cock with the float controlled connections removed;

Fig. 3 is a topV plan view with the cap nut removed;

Fig. l is cross section on line 4l-4t of Fig. 2;

Fig. 5 is a detailed perspective view of the valve member and its stem;

Fig. 6 is a bottom plan view of the valve casing, and,

Fig. 7 is a detailed perspective view of the head end of the float stem.

Referring now to these figures, the auto- .below the casing extension lift the valve suitable construction, is

without matically closing ball or valve member 10 1s,l in my presentv construction, shiftable downwardly to closed position upon va seat llformed around the lower portion of the enlarged valve chamber 12 of thefvalve casing 13. As seen particularly in Fig. 2 this va ve .seat is between the valve chamber 12 inwhich the' ball 10 is movable, and a lower reduced portion 14 communicating with a curved outlet vchannel 15 `into the outer end of which is threadedly connectedthe upper end of theoutlet` tube "16.

The valve casing 13`has a lower extension 17 approximately i 4 portion of the' outlet tube 16, at. 'one side thereof,provided with a' lengthwise bearing opening" for the valve Istem 18, at Iwhose upperfend the ball or valve ried, the lower end of stem 18 projecting when the valve is in closed position on its seat 11.

Valve casing 13 is also provided with an intakeA channel 19 into the lower end of which the upper end of the intake tube 2O is threadedly connected, this intake tube 2.0 having a lower externally threaded portion 21 for passage through the base of a tank 22, and for the reception of a union 23 connectingxthe same with asupply pipe 24.

he lower extension 17 of the valve cas ing has spaced depending ears 25, each provided with an inclined slot 26 opening upparalleling the upper member 10 is carwardly for the reception' of laterally proi Jecting trunnions I27 or lever 28, whose rounded extremity 29 works against the lowerend of the valve stem 18 and acts as a cam thereagainst to oil of its seat when the float descends. For this reason theffloat, as seen at 30 in Fig. l, and which may be of any mounted at one end of its stem Slat the opposite end ofwhich the head or lever 28 is carried, and it is" obvious that when Vthe tank is in normally filled condition, with thevalve 10 closed, it is simplynecessary to further raise the float 30 and withdraw the samefrom between the depending ears 25.

At Vits outer end the valve casing 13 is internally threaded around `the upper portion of the valve chamber 12,for the recep` tion of a threaded capnut 32, so that the valve may be readily reached and withdrawn for purposes of repair and substitution demounting the valve casing, the

of the floatstem head communicating end oi' the intake'channel 19 being likewise readily reached in cases where it may be necessary to plug the same.

It is obvious that, seating as it does downwardly against its seat and in the direction of flow of water through the valve casing, the valve or ball 10 will be held closed both by virtue of its own weight7 and the pressure of water above the same and Vwithin the valve chamber 12, thus permitting the float 1 and its connections to be removed as pre--` viously described, without in `any way ai-` fect-ing the valve. My invention thus presents a construction which is both effective and efficient inv use, which permits of ready accessibility to its several operating parts, and which. in thisV way provides for Veasy f convenient repair and substitution.

l. The combination with a casing, having a valve seat,'and inlet and outlet means on opposite sides of said valve seat, a valve adapted -for contact with said seat and having aidepending stem, the lower portion of said casing being provided with a depending tubular guideslidably receiving said stern7 a pair of spaced parallel ears depending from said tubular guide and provided with inclined slots opening out through the upper portions of the ears, a lever having its rear en d rounded to form a cam engaging the lower end of said depending stem, a

said casing being provided with a depending tnbularguide slidably receiving said stem, a pair of spaced parallel ears depending from said tubular guide and provided with inclined slots, opening out through the upper portions of the ears. a lever having its rear end rounded to form a cam engaging the lower end of said depending stem, and a pair of trunnions extending from said lever forwardly of said cam and detaohably arranged within said slots whereby the lever ymay be readily detached from said ears.
